strcpy using pointers

Question

I\'m trying to write strcpy on my own using pointers and I get an error during runtime.

void str_cpy(char **destination, const char *source) {
//    char *s1         


        

Answer 1

Recently I faced same problem of above one using double pointer strcpy implementation

It might helpful to others below code

 void strcpy_i( char **dst, const char *src )
 {
    *dst=(char *)malloc((strlen(src)+1)*sizeof(char));

    char *tmp=*dst;

    if(tmp == NULL || src == NULL)
    return ;

    while((*tmp++=*src++)!='\0');
}

int main()
{
    char v[]="Vinay Hunachyal";
    char *d=NULL;

    strcpy_i(&d,v);
    printf("%s",d);

 return 0;

}
